http://4crawler.cruiserpages.com/4x4/ForSale/RockSliderZ.shtml#StandardUltimate i'm in the process of getting sliders, and i'm selling my factory side rails (hint hint

). has anyone tried these sliders themselves? i would like some feed back on the customer service (i understand it's an independant fab guy) and how they hold up to hard impacts. the delivery time is almost a month though...but i am willing to wait since they are somewhat cheaper and i like the looks of them more than the eoe or calmini.
